PhD in Electronics for the Internet of Things
Microelectronics and preventing floods? What is the link? This PhD opportunity will develop miniature sensors that last for decades without charging.
Recent developments in microelectronics have allowed electronic circuits to be powered by miniature energy harvesters and even sensors themselves. This has the potential to lead to battery-free Internet of Things devices, for example to alert us to natural disasters such as floods. There are many useful applications for small systems that do not require battery replacement, in sprawling systems such as power grids or transport networks, or in remote structures such as wind turbines or storage systems.
This PhD offers great opportunities to trial your methods in real-life situations, with plenty of opportunity to collaborate with industry. This PhD will work with the world’s lowest-power electronic devices, some of which have been developed in the Bristol Electrical Energy Management (EEMG) research group (bristol.ac.uk/engineering/research/em/). The EEMG at the University of Bristol is a multi-disciplinary team of PhD students, post-doctoral researchers and academics who have developed some of the world’s lowest-power electronic devices.
The PhD can focus either on microelectronic design or on the use of already existing components to develop ultra-long-life sensors, depending on your background. A core research question will revolve around how to power certain functions of smart devices from sensor output signals alone. We are looking to hear from enthusiastic and exceptional students.
Funding: Subject to contracts and eligibility criteria the scholarship, if successfully awarded, covers full UK/EU (EU applicants who have been resident in the UK for 3 years prior to the 1st day of the PhD) PhD tuition fees and a tax-free stipend at the current (RCUK rate 2019 RCUK rate £15,009 which is the pre-tax equivalent of £20,450).

PhD in Wide-Bandgap-Enabled Power Electronics for Smart Grids and Electric Vehicles
Emergence of wide-bandgap power semiconductor devices, especially Silicon Carbide (SiC) & Gallium Nitride (GaN) power devices has opened pioneering avenues for application of power electronics in power systems & electric vehicles. These devices increase the energy conversion efficiency which in turn reduce the power losses & unwanted heat & so contribute to greener energy.
Due to the large band-gap & high critical electric field, these new devices are able to operate under significantly higher electro-thermal stress. This can then be used in the next generation of modular multi-level (MMC) voltage-sourced converters (VSC) in high voltage direct current (HVDC) stations. As a result, the converter will be simplified which in turn enables simpler control, higher energy conversion efficiency & easier fault detection.
A core focus of this research will be to understand the opportunities & challenges in the application of devices in high voltage grid-level & electric vehicle applications. Developing converters will enable comparison between the devices from a performance & reliability perspective. This PhD offers great opportunities to trial new methods in real-life situations, with opportunity to collaborate closely with industrial partners EA Technology, General Electric & Dynex Semiconductor.
The PhD candidate will be supported by two supervisors with different expertise & will be expected to carry out theoretical analysis & experimentation.
Technical support from EA Technology, General Electric and Dynex Semiconductor.
Funding for this research position is subject to competition for the 2021/22 University of Bristol Scholarship scheme only. More information can be found here: http://www.bristol.ac.uk/fees-funding/awards/pg-research-scholarship/
Ideal Candidate requirements would be in Electrical or Electronic Engineering or a related discipline, with knowledge of Power Electronics or Electronic Devices. Further information can be found on the PhD Electrical and Electronic Engineering Admissions Statement.

PhD in Future Aircraft Electric Generators Technologies
This PhD will develop new modelling / predictive algorithms to quantify the life expectancy of high-speed rotating machines operating in a harsh environment. New “smart” technology will be developed to integrate these algorithms into the design of high-speed machines. The idea will be to investigate which parameters that can be readily monitored from the static part of the machine can be linked to parameters on the rotating part of the machine. The successful candidate will develop the models from finite element analysis backed up by validation through experimental testing and where necessary new ways of making the measurements will need to be defined.
These activities are part of a wider industry funded research programme focusing on the concept of the more electric aircraft and as such the work will be supporting the reduction of weight and volume of the machine whilst improving the in-service reliability. Being able to reliably predict the point of failure sufficiently far in advance for action to be taken at the scheduled maintenance point, thus eliminating a costly unscheduled maintenance operation is the intent of this project.

PhD in Holistic Design Optimisation of Power Electronic Converters
What does it take to design a high performance, ultra-compact power electronic systems needed by the growing electric vehicle sector? Or maximise the efficiency of renewable micro-grid converters while minimising their cost?
How can we utilise the full potential of state-of-the-art wide bandgap (WBG) devices that are currently revolutionising the power electronics industry? In order to do this, engineers need a holistic design tool that optimises every element of a power electronics system. Smart automated software is needed to ensure that the systems needed work together to produce the optimal design.
This PhD will focus on developing the software tools needed to holistically optimise power electronic converters. It will involve modelling all the core electrical, thermal and mechanical components in a power converter; developing system models and optimisation routines; and designing, building and benchmarking power electronic hardware and software. The tools that will be developed will utilise the latest power electronic topologies and components to produce state-of-the-art power electronic converters.

Development of the Next Generation of Battery Model Parameterisation Techniques
In this PhD, the student will develop the next generation of experimental techniques used to parameterise battery models. Models are used across the battery industry to replicate the expected operational performance of their physical counterparts, yet they are fundamentally limited by the accuracy of their input parameters. These input parameters are found through ‘parameterisation’ experiments. It is becoming increasingly apparent that parameterisation experiments are not fit for purpose, they are inaccurate and time/cost expensive. Waiting months to parameterise a battery model which you do not trust is a luxury that modern engineering companies cannot afford.
The motivation for the PhD is simple to summarise. Temperature affects every aspect of battery performance, yet the existing state-of-the-art parameterisation experiments confine temperature as a poorly controlled constant. You will lead the development of methods which use temperature as a well-controlled variable, and in doing so you will add an additional dimension to the parameters which define the performance of every battery model. The battery industry is expected to triple in size before 2030. Your contributions will be critical as transport and energy storage is electrified throughout the first half of the 21st century.
You will begin with an experimental evaluation of the established battery model parameterisation techniques, before developing your own methods which focus on the use of advanced thermal control and transient thermal conditions. Alongside experimental work, you will develop your own understanding of battery model design and operation. Work will involve interaction and collaboration with a close-knit community of UK-based battery researchers, and you will have opportunities to travel to other institutions and conferences in the UK and beyond, to further your learning and ultimately present your key findings.
